Examples

End-to-end Backup and Recovery examples are also available in the Getting Started Section

Backup Target

The Backup Target CRD specifies the backup storage media. Trilio supports either AWS S3 compatible object storage or NFS. A user can configure multiple backup targets and choose the target when an Application CR is created. All backups that are created for that the Application will be saved on the backup target specified in Application CR spec. Once a backup target is chosen for an Application, it cannot be changed.

Example 1 - S3 Target: AWS

Sample YAML file for AWS based S3 bucket

apiVersion: triliovault.trilio.io/v1
kind: Target
metadata:
  name: demo-s3-target
spec:
  type: ObjectStore
  vendor: AWS
  objectStoreCredentials:
    url: "https://s3.amazonaws.com"
    accessKey: "AaBbCcDdEeFf"
    secretKey: "BogusKeyEntry"
    bucketName: "S3_Bucket_US_East"
    region: "us-east-1"

Example 2 - S3 Target: Non-AWS

Sample YAML file for non AWS S3 compatible bucket. The only difference between this spec and AWS S3 spec is the explicit specification on URL.

apiVersion: triliovault.trilio.io/v1
kind: Target
metadata:
  name: sample-target
spec:
  type: ObjectStore
  vendor: Ceph
  objectStoreCredentials:
    url: "http://bucket.s3.dualstack.region.acme.com/key"
    accessKey: "XXXXXXXXXXXXXXXXXXXX"
    secretKey: "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"
    bucketName: "datahub-dev"
    region: "us-west-1"

Example 3 - NFS Target Example

Sample YAML for NFS share.

apiVersion: triliovault.trilio.io/v1
kind: Target
metadata:
  name: sample-target
spec:
  type: NFS
  vendor: Other
  nfsCredentials:
    nfsExport: 192.168.1.1:/src/nfs/kubedata
    nfsOptions: nfsvers=4

BackupPlan

The BackupPlan CRD specifies the backup job. The specification includes the backup schedule, backup target and the resources to backup. Trilio supports three types of resources to backup and an BackupPlan CR may include combination of these resources.

This BackupPlan CR defines a set of resources to backup.Resources can be defined in the form of Helm release, Operators or just bare k8s api resources.

In this release, Trilio supports defining resources to be backed up using :

  1. Helm releases

  2. Operator-based application instances

  3. Label-based selection of resources

Type: Custom Label - Example 1

The following sample BackupPlan CR specifies a Label-based selection of resources. In this example any resource has a label app with valuegcp-compute-persistent-disk-csi-driver will be backed up.

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupConfig:
    target:
      name: sample-target
    schedulePolicy:
      fullBackupCron:
        schedule: "* 0 1 * *"
      incrementalCron:
        schedule: "* 0 * * *"
  backupNamespace: triliovault-integration
  backupPlanComponents:
    custom:
      - matchLabels:
          app: gcp-compute-persistent-disk-csi-driver

Type: Custom Label - Example 2 - Multiple Labels

The example below explains how a backupPlan CR can be used to protect data using multiple labels.

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupNamespace: triliovault-integration
  backupConfig:
    target:
      name: sample-target
  backupPlanComponents:
    custom:
      - matchLabels:
          app: frontend
      - matchLabels:
          app: backend

Type: Helm - Example 1 - Single Helm Release

The following sample BackupPlan CR that specifies Helm release based resources to backup. Trilio automatically discovers the resources that belong to the release and backups the helm chart as whole. The release that this example backups is mysql-releasename.

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupConfig:
    target:
      name: sample-target
    schedulePolicy:
      fullBackupCron:
        schedule: "* 0 1 * *"
      incrementalCron:
        schedule: "* 0 * * *"
  backupNamespace: triliovault-integration
  backupPlanComponents:
    helmReleases:
      - mysql-releasename

Type: Helm - Example 2 - Multiple Helm Releases

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupNamespace: triliovault-integration
  backupConfig:
    target:
      name: sample-target
  backupPlanComponents:
    helmReleases:
      - sample-release
      - sample-release1

Type Operator - Example 1

Another type of resource that Trilio supports is an Operator-based applications and the following YAML snippet describes the BackupPlan CR that includes the operator based application.

Example 1a

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupNamespace: triliovault-integration
  backupConfig:
    target:
      name: sample-target
  backupPlanComponents:
    operators:
      - operatorId: sample-mysqlcluster
        customResources:
          - groupVersionKind:
              group: "mysql.presslabs.org"
              version: "v1alpha1"
              kind: "MysqlCluster"
            objects:
            - sample-mysqlcluster
          - groupVersionKind:
              group: "mysql.presslabs.org"
              version: "v1alpha1"
              kind: "MysqlBackup"
        operatorResourceSelector:
          - matchLabels:
              app: mysql-operator
              release: sample-release
        applicationResourceSelector:
          - matchLabels:
              app.kubernetes.io/managed-by: mysql.presslabs.org
              app.kubernetes.io/name: mysql

Example 1b

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupNamespace: triliovault-integration
  backupConfig:
    target:
      name: sample-target
  backupPlanComponents:
    operators:
      - operatorId: etcd-cluster
        customResources:
          - groupVersionKind:
              group: "etcd.database.coreos.com"
              version: "v1beta2"
              kind: "EtcdCluster"
            objects:
              - etcd-cluster
        operatorResourceSelector: # sa, clusterrole, clusterrolebinding, deployment
          - matchLabels:
              app: etcd-operator
              release: sample-release
        applicationResourceSelector: # svc: etcd-cluster, etcd-cluster-client
          - matchLabels:
              app: etcd
              etcd_cluster: etcd-cluster

Type Operator - Example 2 - Multiple Operators

The YAML definition below provides an example of how multiple helm apps can be protected through the BackupPlan CR.

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupNamespace: triliovault-integration
  backupConfig:
    target:

              release: sample-release
        applicationResourceSelector:
          - matchLabels:
              app.kubernetes.io/managed-by: mysql.presslabs.org
              app.kubernetes.io/name: mysql
      - operatorId: sample-fluxcd-helm-release
        customResources:
          - groupVersionKind:
              group: "helm.fluxcd.io"
              kind: "HelmRelease"
              version: "v1"
            objects:
              - redis
        operatorResourceSelector:
          - matchLabels:
              app: helm-operator
              release: helm-operator
        applicationResourceSelector:
          - matchLabels:
              app: redis
              release: redis

Type: Operator - Example 3 - Helm based operator

Operator based applications can also be protected by providing the helm release name for the Operator resources.

        applicationResourceSelector:
          - matchLabels:
              app: redis
              release: redis

Type: All - Example with all 3 Application Types -1

The BackupPlan CRD is an extremely flexible CRD within which multiple application components can be specified.

apiVersion: triliovault.trilio.io/v1
kind: BackupPlan
metadata:
  name: sample-application
spec:
  backupNamespace: triliovault-integration
  backupConfig:
    target:
      name: sample-target
  backupPlanComponents:
    custom:
      - matchLabels:
          triliobackupall: all
    helmReleases:
      - sample-release
    operators:
      - operatorId: sample-mysqlcluster
        customResources:
          - groupVersionKind:
              group: "mysql.presslabs.org"
              version: "v1alpha1"
              kind: "MysqlCluster"
            objects:
            - sample-mysqlcluster
          - groupVersionKind:
              group: "mysql.presslabs.org"
              version: "v1alpha1"
              kind: "MysqlBackup"
        operatorResourceSelector:
          - matchLabels:
              app: mysql-operator
              release: sample-release
        applicationResourceSelector:
          - matchLabels:
              app.kubernetes.io/managed-by: mysql.presslabs.org
              app.kubernetes.io/name: mysql

Backup

The Backup CRD takes a backup of the resources specified in the BackupPlan spec. It takes either a Full backup or Incremental Backup. The first backup of the Application will always be a Full backup even if the user specifies their backup type as Incremental.

Incremental backup includes all the YAML files and delta changes to PVs data. Incremental backups are not complete by themselves and relies on all the previous incremental backup and the full backup.

Example 1 - Full Backup

The following sample Backup YAML for Full backup

apiVersion: triliovault.trilio.io/v1
kind: Backup
metadata:
  name: sample-backup
spec:
  type: Full
  scheduleType: OneTime
  backupPlan:
    name: sample-application

Example 2 - Incremental Backup

Sample Backup YAML for incremental backup

apiVersion: triliovault.trilio.io/v1
kind: Backup
metadata:
  name: sample-backup
spec:
  type: Incremental
  scheduleType: OneTime
  backupPlan:
    name: sample-application

The scheduleType field is to specify if the backup should follow the backup schedule provided in the backupPlan or if it should be a one-time backup only.

Restore

The Restore CRD specifies the backup that resources need to be restored from. Resources can be restored to the same namespace or a different namespace. If a backup target with existing backups are created to a different cluster, those backups can be restored to the cluster. A migration or disaster recovery use case can be implemented using this functionality.

Example 1 - Restore from a specific backup

Sample YAML file to restore from a specific backup. The backup is identified by name sample-backup.

apiVersion: triliovault.trilio.io/v1
kind: Restore
metadata:
  name: sample-restore
spec:
  source:
    type: Backup
    backup:
      name: sample-backup
  restoreNamespace: triliovault-restorens

Example 2 - Restore last successful backup

Sample YAML that restores latest backup of a BackupPlan.

apiVersion: triliovault.trilio.io/v1
kind: Restore
metadata:
  name: sample-restore
spec:
  backupPlan:
    name: sample-application
  restoreNamespace: triliovault-restorens

Example 3 - Skip Restore

Trilio provides the capability to Skip the restoration of objects if they already exist in the namespace. This is achieved by using the skipIfAlreadyExists field within the Restore custom resource

apiVersion: triliovault.trilio.io/v1
kind: Restore
metadata:
  name: sample-restore
spec:
  source:
    type: Backup
    backup:
      name: sample-backup
  skipIfAlreadyExists: true
  restoreNamespace: restore-namespace

Example 4 - Patch Restore

Trilio provides the capability to Patch resources if they already existing in the namespace during the restore

apiVersion: triliovault.trilio.io/v1
kind: Restore
metadata:
  name: sample-restore
spec:
  source:
    type: Backup
    backup:
      name: sample-backup
  patchIfAlreadyExists: true
  restoreNamespace: restore-namespace

Example 5 -Restore From Specific Location - Migration Scenario

apiVersion: triliovault.trilio.io/v1
kind: Restore
metadata:
  name: sample-restore
spec:
  source:
    type: Location
    location: e90ce943-a0ce-11ea-93b2-42010a8e0038/66777359-a0d1-11ea-93b2-42010a8e0038
    target:
      name: sample-target
  restoreNamespace: restore-namespace

Restore by location is not available in 1.0.0.
